HARRY HERTZBERG, or BRoo K YNQNEw YORK MOP AND wnmenn comninnnApplication filed November 26, 1928. Serial No. 321,925.

This invention relates to mops for household use and the like andparticularlyto that type of such mops which have a device for wringingthe mop cloth or cords attached to the mop structure.

It is the object of this invention to provide a device of this kindwhich consists of very few parts and yet is of rigid construction andextremely simple in operation.

It is a further object of the invention to provide a wringing devicewhich is always ready to be operated without the necessity to placeeither mop or wringer in acertain position.

WVith these and other objects in view which will become clearer as theappended description progresses, the invention resides in a novelcombination of parts and details of construction shown on theaccompanying drawings which form a material part of this disclaims.

In the drawings:

Fig. 1 is a perspective view of my mop with wringer.

Fig. 2 is a detail cross section of the wringer of Fig. 1 showing thetoothed rollers in engagement with the mop material.

Fig. 8 is a detail showing the mounting of the lower roller and meansfor removing the same and the mop material from the supporting frame.

The frame 10 comprises a fiat bar bent upon itself at the center to formprojection 11, and bent at its ends to form a yoke having rollersupporting brackets 12 and 12 The projection 11 is inserted into anaxial slot at the lower end of mop stick 13, collar 14 encloses theslotted portion of the mop stick, serving to reinforce the same, andpins 15 hold these parts in place.

In journal apertures of brackets 12 and 12 and in operative relation,are rotatably mounted on shafts 19 and 21 toothed rollers 16 and 17loosely meshing with each other, of these rollers 16 is fastened to itsshaft to be rotated thereby, while 17 is loosely mounted on its shaft21. Between these rollers, mop material 18 is held incompressedcondition.

The mop material 18 consists preferably of so a continuous cord coiledin loops of equal closure and are finally pointed out in the size lyingalongside of each other and stitched together toform an endless mopcloth.

' On the shaft 19 of roller 16 is fitted a knob 20, preferably keyedthereto, whereby :roller 16 may be rotated. -Ro1ler 17 meshing withroller 16'is caused to rotate thereby so that the various parts of mop18 may be wrung. The

ends of shaft 21 which holds'roller 17 journalledin brackets12 and 12are covered by resilient caps 22 which prevent longitudinal motion ofthe shaft. These caps may be bent outward into the dotted position ofFig. 3 and rotated 'about screw 23-to release shaft 21 for itsremovaland to release roller 17 for exchange of the mop cloth. After'thisfexchange and replacement of roller 17 and shaft 21the'caps areplaced in their original posi tion and by their resiliency lie againstthe vertical side of the supporting bracket.

It will appear clearly from the above description that this mo andwringer combination is a compact an efficient structure, and that theassembly of its severalparts is very simple, particularly as the rollerswhich sup port the mop material are also the means for wringing it andfurthermore serve to hold this material stretched to lie fiat on a floorto be mopped. The wringing operation may be started at any desiredmoment as the endless mop material is always in'the same positionrelative to the rollers.

However, while the preferred form of the device has been describedhereinabove, as an example of the many ways of constructingit,it isunderstood that such changes may be made in the arrangement of parts andthe construction of minor details thereof, as come within the scope ofthe invention as claimed, with out departure from the spirit of theinvention.

What I claim as new and desire to secure by 7 Letters Patent is:

1. In a device of the character described, a yoke formed to providemeans for attachment to a mop handle, a pair of parallel lugs atopposite ends of said yoke, a pair of toothed rollers operativelymounted on shafts held in fixed position within bearing apertures insaid yoke, a handle on the shaft of one of said rollers for rotating thesame, the second roller being loosely mounted on its shaft adapting saidshaft to be removed from said yoke through one of the bearing apertures.

2. The combination with a mop stick of a wringer comprising a yoke,toothed rollers rotatably mounted within said yoke on shafts laterallyfixed within bearing apertures of said yoke,mopmateria1 supported inthespace between said. rollers to be propelled and wrung thereby,fastening means formed integral with said yoke for holding it rigidlyconnected to said mop stick, one of said rollers being adapted fordisengagement from its shaft and said shaft being removable from saidyoke in axial direction to permit release of. said mop material.

' 3. The combination with a mop stick of a yoke having a plate integraltherewith adapted to enter a longitudinal slot in said mop-stick andfastening means passing transversely through said plate and mop stick, apair of rollers mounted on shafts fixed Within apertures in said yoke,mop material forming an endless looped sheet supported between saidrollers to be propelled and wrungv thereby continuously one of saidrollers being detachable from its shaft and said shaft being detachablefrom said yoke and meansfor holding said shaft longitudinally fixedwithin said yoke.

Signed at Brooklyn, in the-county of Kings and State of New York, this17th day of November, A. D. 1928'.
